Cam Precision Plastic Forming And Numerical Simulation Of Camlobe

Camshaft is main part of engine gearing with the feature of complicated structure, not well-proportioned bear weight and precision high. The disadvantage of traditional holistic cam manufacture technics and the highly exceptive requirement for cam manufacture conflicted. And this proceeding the new-coming and developing technics for camshaft manufacture. Constructional camshaft manufacture technics is a method to assemble the cam, the shaft-neck, the core-shaft and other fittings together. It is modern manufacture technics which has tied in the design, the analysis of capability and the chosen of material for camshaft. The traditional holistic camshaft manufacture method has been changed radically and the new method is a great breakthrough for the camshaft manufacture technics. This new method answers for the improving manufacture principle, it is a good way to improve the precision, the efficiency and it's also a good way to decrease the cost. Constructional camshaft manufacture technics is the key method for camshaft manufacture's developing and improving, it makes innovation and span come true. It can be used not only for the renovation of common camshaft manufacture and improvement of automatic technics but also for valves topmost camshafts and compact structure engine, Especially in now days it's a world emphasizing the decreasing of air-pollution and protection our circumstance. So it's an exigent way to manufacture these camshafts answering for the high capability and low pollution of engine. Therefore, it is quite necessary to study on constructional camshaft connection technics, the manufacture method for camshaft and the development of automotive constructional mechanism. Traditional camshaft molding technics always has disadvantages as complexity, time-consuming and the shape and precision of camshaft is not very well. Disfigurements are appeared invariably.Therefore, it has quite an important meaning to study on the development of camshaft which is one of the three key technics for constructional camshaft. This...
